Is a genius born or made?
VERY SO often, we hear of them - calculating prodigies. These are
the people who can quickly and accurately solve complex
mathematical calculations. Until recently, we had our own
Lilavathi Devi who was famous for her arithmetical feats. Now,
France is all-agog about a young man called Rudiger Gamm who has
been wowing TV audiences there with his astounding ability to
calculate the fifth root of a ten-digit number within a few
seconds. Are these people geniuses? Or are they savants, meaning
those who are profound and learned in one particular area or
field but ordinary (or even unimpressive) in others? How did they
get their abilities? How does one define a genius? Can any one
attain such proficiency?
These questions are being addressed today in several laboratories
of cognitive psychology around the world. Some are studying how
so many taxi drivers of the greater London area are able to store
and retrieve enormous amount of data about the route maps and
locations of the lanes and bylanes of the sprawling city.
(Incidentally this ability may not be limited to cabdrivers in
London alone; look at some of the taxi or scooter rickshaw
drivers of Delhi or Chennai). Some others are studying musical
prodigies and whether listening to music expands the capabilities
of our minds. Yet others look at chess players and have attempted
to train people into becoming chess champions. A success story in
this case is that of Miss Judith Polgar and her two sisters from
Hungary, who were trained by their parents to become world-class
champions. Their father Dr. Laszlo Polgar has written a book on
this subject entitled Bring up Genius.
Such stories fly in the face of the conventional notion that a
genius is born and not made. They suggest that deliberate
practice can aid in making a genius.Thomas Alva Edison said it
succinctly - "1 per cent inspiration and 99 per cent
perspiration". So, is it that geniuses do not just spring from
the womb but need to be made, prepared, processed? Put another
way, can any one with appropriate talent be made into a genius?
Long-term and short-term memories
Laszlo Polgar thinks so, and so does Anders Ericsson of Florida
State University. The January 13th issue of The Economist
highlights his arguments with the title "Practice makes perfect".
Ericsson does not subscribe to the idea that a genius is born so,
nor that he is possessed with a special set of genes. Instead, he
believes that a genius - be it Mozart, Gauss or Einstein- also
works hard at it. He suggests that they have developed powerful
memories for storing information about topics that they are good
at. They seem to be able to keep important information in special
areas of their brain, and access and use the data for working
their genius act.
Neuroscientists distinguish between short-term or "working"
memory and long-term or episodic or "storage" memory. We utilize
our short-term memory for certain kinds of activities; these may
involve immediate tasks such as recognizing our waiter in an
unfamiliar restaurant in the restaurant we have gone for dinner,
and waving to him to catch his attention for service. We forget
about him after a few days. He is not stored in our long-term
memory. But information about a topic of importance, say relating
to our profession or our bank account, or our relatives, is
stored in long-term memory for retrieval and reworking. Dr.
Ericsson believes that it is this long-term memory that is
crucial for the impressive performance of a prodigy be it in
chess, music, mathematics or even typing. He further believes
that any one can work on his long-term memory area and learn the
trick to store information there for later retrieval. It needs
practice, hard partice. But is that not what made M. S.
Subbalakshmi, (the late) Madurai Mani Iyer, or Ravi Shankar what
they are? They did not just dream up their swara chanchara out of
nowhere. They learnt, practised and perfected their art, and this
experience has helped them create new phrases, patterns and
tunes. To be a creative individual is not a cake- walk. It
requires effort, single-minded pursuit of the chosen area of
activity, often at the cost of other tasks. The apocryphal story
of the absent- minded professor boiling his pocket-watch in water
while holding the egg for breakfast in his hand illustrates this.
Einstein was not too particular about how he dressed or whether
his hair was combed, it did not occur to him too often to do so!
(Hence the dishevelled appearance of several contemporary
Einstein wannabes!)
Looking into the brain at work
That wizards and geniuses need to work and work hard at it is
accepted - hence the "perspiration". What they make out this
effort is the interesting question. Some answers are coming forth
from neuroscience laboratories, which support Dr. Ericsson to
some extent. The mathematical wizard Rudiger Gamm agreed to
participate in one such experiment conducted on him by Dr.
Nathalie Tzourio-Mayozer of the University of Caen, France and
her associates. They asked him to perform some of his
mathematical feats, and as he was doing so, they monitored
various regions of his brain using the technique called PET
(positron emission tomography), which helps map regions of brain
that are activated by the task. They found that he was
continually switching between short-term, effort-requiring
storage strategies and highly efficient long-term memory encoding
and retrieval. In other words, he was using his long-term memory
to "park" or store the working results he needed to complete his
calculations. This strategy of storing using extra memory space
is what high speed high-capacity digital computers do. Such
"parking"lets him avoid the pitfall of losing crucial
intermediate steps - something we non-experts constantly lose
ourselves in. In essence then, Gamm uses different (additional)
brain areas for his calculations, a strategy that we usually do
not do. The title of the Tzourio-Mayozer paper (that appeared in
the January issue of Nature Neuroscience) says it all: "Mental
calculations in a prodigy's sustained by right prefrontal and
medial temporal areas (of the brain)". These are areas in the
brain connected with long-term memory. While prodigies like Gamm
use them for their feats as additional areas, which we "normal"
people do not.
Interestingly, Gamm is otherwise ordinary. Other than his
superior ability in mathematics, he is as "normal" as you and me
in other areas of activity. Furthermore, he was not always a math
prodigy. He was not a born prodigy but developed this skill only
6 years ago, through daily practice of four hours of memorization
(much the way musicians learn their art). This is interesting
since many believe that prodigies display their prowesses already
at a very tender age; one hears more of child prodigies, not an
adult one! Gamm shows that it is possible to groom and bloom in
later years too.
How to make a genius
Does this mean enhanced long-term memory strategy is the key to
prodigious performance? Dr. Ericsson would think so. Indeed he
has taken "normal" people and trained them to prodigy level
performance in number memory tasks through practice sessions that
lasted a year or so. Come to think of it, is this not what great
musicians and sportsmen do? Ustad Ali Akbar Khan has been known
to practise on his sarod for hours each day; Pete Sampras and
Michael Jordan practise tennis and basketball everyday. Such
enormous practice and preparation (99 per cent perspiration)
makes much of the technique and methodology second nature to
them, allowing for leaps of imagination to hold sway
(inspiration).
Granted that maestros need practice to stay at their
extraordinary levels of creativity and accomplishment, is the
reverse true? Can practice produce a genius? This is the debate
that is raging the field now. Ericsson argues that given ten
years of intense practice, anyone should be able to become a
prodigy. Countering this is the "Mozart argument", advanced by
many others who says that mere hard work does not produce a
Mozart. It may produce a craftsman but not necessarily an artist,
technical prowess but not talent. There might be a genetic
component - a predisposition, a susceptibility or trait that is
necessary to impart the "inspiration" or the creative leap
component. You may well use long term memory to "park" data,
material, connections, thought - but the availability of such
parking space or memory bins may not suffice. What you put in
there is important. Mr. Gamm is impressive in his prodigious
arithmetic ability, but until he displays originality, creativity
or a leap of thought that advances our knowledge, he will not be
considered a genius. May we wish him a Mozartian future?
The Mozart effect: listening to genius music
The child prodigy and genius Wolfgang Amadeus Mozart has recently
become an icon among neuroscientists and educators for another
reason. It was in 1993 that the physicist Gordon Shaw of the
University of California and the concer cellist and cognitive
scientist Frances Rauscher studied the effect of listening to
Mozart's music (Sonata for Two Pianos in D Major, K 448) on the
problem solving abilities of over 50 college students. They
reported seeing a temporary enhancement in spatio-temporal
reasoning in the students upon listening to the music.
Unfortunately, the report is still not clear of controversy,
since apparently their results are not reproduced by others. Some
are skeptical about the whole affair (see the Skeptics
Dictionary, skepdic.com, on The Mozart Effect). There are others
who are so enthusiastic about the effect of music on body and
mind that they even claim that music cures diseases and heals
injuries. One Don campbell, who has trademarked the expression
The Mozart Effect, claims that music can cure just about anything
that ails you. (Some have asked that if that be so, why was
Mozart himself so frequently sick, and why aren't the world's
smartest, most spiritual and most athletic people Mozart
specialists).
We had discussed the effect of music on the mind earlier in these
columns (May 2, 1993; July 4, 1996). As on date, there are no
reproducible and scientifically rigorous studies that show music
to heal diseases or physiological disorders. Studies reported to
date on this topic are too casual, too selective and leave too
many parameters open to make a sharp conclusion. Many of us would
like to believe that music has beneficial effects. Surely it
does, it soothes the mind, calms the nerves, relieves tension,
makes you relaxed and even helps you think up an occasional new
idea. But to assert that `plants grow better with music' or 'Raga
Anandabhairavi relieves hypertension' is not acceptable for want
of rigorous proof or reproducible results. To say that listening
to Mozart Horn Concerto while applying shampoo to your hair cures
baldness (as a Japanese firm did a few years ago) is even worse.
Which music affects the most
It is generally coming to be accepted that music enhances the
mind of the listener. What type of music is the question- Mozart
or Madonna, D. K. Pattammal or Daler Mehndi? What specific
musical elements are required? Some studies by the Illinois
neurologist John Hughes suggest that sequences repeating every 20
or 30 seconds may trigger the strongets response in the brain,
because many functions of the cetral nervous system (such as
brain wave patterns) occur at this rate. Mozart most often peaks
at this rate. Some hospitals and care centres play the Gregorian
Chants, which have a variable but soothing cadence. The rigorous
science behind these instances needs to ne worked out before we
accept them as truly beneficial.
The actual type of music that enhances our mind will most likely
depend on the culture we are steeped in. While there may be
common determinants, the actual music that affects the most may
also vary from one individual to another. It would thus be
interesting to hear from readers about Indian music compositions.
Professor Lakshmithathachar of the Academy of Sanskrit Studies,
Melkote, with whom I discussed this matter a few years ago, said
that the chanting of the Medha Suktam from the Taitreya
Upanishad, in the proper metre or chandas, is believed to enhance
the mind. There must be similar passages or chants from the lofty
books and psalms of Christianity, the Holy Koran, the Buddhist
Pects, the Zend Avesta, the Granth Saheb and others. Lastly, the
type and variety of music that appeals to and enhances the mind
of an individual may also change or increase with time. My own
list has grown over the last forty years- Madurai Mani Iyer's
Shanmukapriya, Ali Akbar Khan's Marwa, Ravi Shankar's Jogeshwari,
MS's Nadanamakriya, Schubert's Impromptus for the Piano, Mozart's
Concerto for Two Pianos and Orchestra (Lodron, KV 242), and most
recently the beautiful blend of Gregorian Chants and Karnataka
Raga Alapana, between Dominique Vellard of France and Aruna
Sairam of India, which is both mutually compatible and enhancing.
